This image from NASA's Dawn mission reveals the creeping dawn over the north pole of the giant asteroid Vesta now that sunlight is shining over that area. The mosaic is composed of 5 images obtained by Dawn's framing camera on Aug.26, 2012, while Dawn was at an altitude of about 4,000 miles (6,000 kilometers).Dawn's north pole is centered in this image and still in the dark.The mosaic shows two large impact craters, one relatively fresh with no smaller impacts on its floor and a second larger and older one with many smaller impacts on its floor.
